IM PROVEMENT IN GAS-R ETORTS.

The Schedule referred to in these Letters Patent and making part of thename.

To all whom it may concern:

Be it known that I, JAMES H. SMITH, of Newark, in the county of Lickingand State of Ohio, have invented a new and useful Improvement inGasdtetorts; and I do hereby declare the following to be a full andcorrect description of the same, reference being had to the accompanyingdrawing, in which.

Figure 1 is a longitudinal vertical central section of an ordinaryretort having my improvement applied.

Figure 2 is a similar section of a through-retort with the sameimprovement.

The same letter marks the same part in both figures.

The nature of my invention consists in so constructing the retort thatthe-gas resulting from the distillation of the coal or othergas-generating material shall escape from the opposite end of the retortfrom that at which the charge is introduced, and shall, in its passageto the outlet, encounter the surfaces of plates so placed that thevapors and gaseous products must pass alternately under and over them,the object being to subject the vapors to such a heat as to secure theproduction uf a fixed gas, which will not be condensed in a condition tobe condensed and washed out in the tar, oil, 860. In the drawing- Amarks the body of the retort;

B, the mouth-piece;

G O, &c., the interposing plates;

D, the stand-pipe; and

E, the front or feed end of the retort.

. The plates G are affixed to the walls of the retort, near .its rearend, and extend alternately fi'om the top to near the bottom of theretort, and from the bottom to near the top of the same, in the mannerclearly shown in the drawing, so that all the vapors generated in thefront chamber E will be obliged to pass over both surfaces of theseheated plates before escaping into the staud-pipe and being delivered tothe hydraulic-main.

Having thus described my invention,

What I claim, and desire to secure by Letters Patcut, is-

The combination, with a gas-retort, of any desired number of plates, 0,attached alternately, and by any convenient means, to the top and bottomof the retort, near its rearor outlet end, substantially in the mannerand for the purpose described.

The above specification of my said invention signed and witnessed atNewark this 30th day of January, A. D. 1871.
